By popular demand, we are publishing the type of
food that will be served at each security lunch this quarter.
By unpopular demand (i.e., at the request of one of the
crypto grad students), we are "encrypting" the food selections
again this quarter.

The food selections are encoded in the following integer, which is
the product of primes p and q:

To recover the food selections for the quarter, factor N into
primes and look at the larger factor (call it p).
Break p into bytes and arrange the bytes from most significant
(at the left) to least significant (at the right).
The least significant byte of p is the constant 0x01.
The next bytes indicate the lunch selection for the October 8 lunch, the
October 15 lunch, the October 22 lunch, and so on.
In diagram form, the bytes of p look like this:
